Pop singer Justin Bieber has complained that his head hurts after he accidentally walked into a glass door.
According to Us magazine, the 16-year-old star walked into a revolving door at the hotel, with waiting photographers capturing the accident.

"What happened was, I thought it opened, but obviously it didn't and I walked right into the window."
